Dynamic Analysis of a Novel Installation Method of Floating Spar Wind Turbines

open access: yesJournal of Marine Science and Engineering, 2023
This paper presents the performance of a new, floating, mono-hull wind turbine installation vessel (Nordic Wind) in the installation process. The vessel can transport pre-assembled wind turbines from the marshalling port to the offshore installation site.

Separation of medical nanopowder from the natural minerals by supercritical CO2

open access: yesMongolian Journal of Chemistry, 2014
Nano-sized medical raw material has been derived from the medical quality natural spar (CaCO3) without the use of chemical salt. The theoretical base of the method consists in the transferring and keeping CO2 to a supercritical state during thermo ...
